[CentOS] Deciding when to do system encryption

Hello All,

I have read that system encryption slows a computer down. However, I am more interested in when to use it. Consider the following scenarios:

1. You have a server in a secured server room on a rack (is there any need and advantage to having system encryption in this particular case) 2. you have a server sitting in an office that is accessible by everyone 2. You have a desktop 3. You have a laptop

So my questions are: What situations/scenarios do you consider before implementing system encryption? I guess at the end of the day, I am trying to figure out the best practices.

Regards, B.I.
